This section gives to examples to get started with particle plots.

	# Open the ~~export=ed~~ particle VTK files in VisIt (as described above)		=== Particle Plot using "Cells" ===
	# ~~Choose~~ icon to ~~add~~ "~~Glyph~~" in the tool ~~bar~~ (~~it is also~~ in the ~~"Filters" menu along with many more options~~)
	# In the "Add" icon menu, choose scalar ~~component~~ to plot for the "Pseudocolor..." submenu (only scalar quantities are in the menu; see [[#Using Expressions\|below]] to convert components of tensors and vectors into ~~expressions~~).		The preferred visualization is to export to an unstructured grid (<b>-U</b> option in [[ExtractMPM]]) where each material point becomes a cell in an a grid. Furthermore, the cells are transformed to reflect the particle deformation. Plotting such files is easy:

			# Open the exported particle VTK files in VisIt (as described above).
			# In the "Add" icon menu, choose simulation result to plot for the "Pseudocolor..." submenu (only scalar quantities are in the menu; see [[#Using Expressions\|below]] to convert components of tensors and vectors into scalars for plotting).
			# Once you have a plot, you can click and drag with mouse to change the viewing position.
			# Choose simulation result to plot from menu in second row of tool bars. (for [[#Vector and Tensor Plotting\|tensor or vector quantities]], choose the component to plot from the second menu).

			=== Particle Plots using Pseudocolor Attributes ===

			If you use the <b>-V</b> option in [[ExtractMPM]], the VTK files will have only point data. To plot such files as a particle-based plot:

			# Open the exported particle VTK files in VisIt (as described above)
			# In the "Add" icon menu, choose scalar quantity to plot for the "Pseudocolor..." submenu (only scalar quantities are in the menu; see [[#Using Expressions\|below]] to convert components of tensors and vectors into scalars for plotting).
	# You can click "Draw" icon to get an initial plot, but next step is need to make it look better.		# You can click "Draw" icon to get an initial plot, but next step is need to make it look better.

Instead, ~~pick a~~ size ~~for good visualization (using~~ smaller ~~than particle~~ sizes).		# In the "Add" icon menu, choose scalar quantity to plot for the "Pseudocolor..." submenu (only scalar quantities are in the menu; see [[#Using Expressions\|below]] to convert components of tensors and vectors into scalars for plotting).
			# Choose "Pseudocolor..." from the "PlotAtts" menu to customize the geometry as explain in [[#Particle Plots using Pseudocolor Attributes\|above]]. You cannot, however, scale size to "meansize." Instead, set an absolute size slightly smaller the material point sizes (or whatever size looks best).
